Answer:

8

Step-by-step explanation:

shirts = 10, price per shirt = $9

shirts = 25, price per shirt = $8.40

Linear equation be:

y = mx + b

x = 10 , 25

y = 9 , 8.40

9 = 10m + b  

8.4 = 25m + b

9 = 10 m + b  b = 9 - 10m

8.4 = 25m + b 8.4 = 25m + 9 - 10m

8.4 - 9 = 15m m = -0.6/15 = -0.04

m = - 0.04

b = 9 - 10m = 9 - 10(-0.04) = 9+0.4 = 9.4

b = 9.4

The linear equation =

y = mx + b

y = -0.04x + 9.4
